Provide "Source Path" with includes/excludes pattern capability for JBoss Rules Eclipse IDE (3.1-M1 currently validates _all_ .xls files in project)

The Eclipse "Drools Builder" is validating every Excel (.xls) in my rules project.

Apparently this feature was added to 3.1-M1 by Kris. I really like the idea of validating decision tables in Eclipse, my issue is that we have FIT tests (in Excel) in a separate source folder in our "rules project". These .xls files are falsely being identified as decision tables with a ton of problems. Validation also seems to take much longer than it does with the 3.0.x branch (like from 30 seconds in 3.0 to to 5 minutes in 3.1 !?!?). Though the two issues may be related.

A common way of dealing with this problem in Eclipse is to allow for ant-like "source path include/exclude" patterns.

i.e. exclude test/*/.xls

For that matter it would be nice to have the same thing for standard DRL files. The validation of a large rule base can take some time and randomly results in exceptions much of the time. Once I've tested and verified a set of rules I could (optionally) exclude them from validation.
